RDF Triple Store-ORA-55320: Model Error Occurred, after Upgrade to Oracle 12c (Doc ID 1997133.1)

Last updated on APRIL 08, 2022

Applies to:

Oracle Spatial and Graph - Version and later
Information in this document applies to any platform.


After upgrade from to 12c, following exception occurs whenever we use the replace option in SPARQL motion script while loading data in RDF Triple store.
Using the append option was working fine, however using replace threw exception.
The new Oracle 12c instance has these additional fields, which were not present in Oracle 11.2 and thus are causing compatibility issues .

Caused by: java.sql.SQLException: ORA-55320: model Error occurred while dropping model:ORA-00904: "MODEL_TYPE": invalid identifier
format_error_backtrace is:
ORA-06512: at "MDSYS.SDO_RDF_INTERNAL", line 12101
